The purpose of this study was to investigate the effect of dietary pistachio hull extract (PHE) on physiological responses of common carp Cyprinus carpio following handling stress. Fish were fed five experimental diets supplemented with 0, 0.5, 1.5, 4.5, 9 g PHE/kg diet. At the end of the experiment, all fish (n=12) in each tank were subjected to acute handling and air exposure stresses. Obtained results showed that fish fed PHE at 0, 0.5, 1.5 g/kg diet had significant increase (P<0.05) in glucose in comparison with initial time (before subjected to stress). These results indicate that different levels of dietary PHE failed to reduce cortisol levels of serum after stress. According to results, it can be concluded that 1.5 g PHE/kg diet added to the diet has a good effect on response to stress in common carp.
